成功解决Error: Cannot find module 'html‐webpack‐plugin'

我的webpack.config.js

var htmlwp = require('html‐webpack‐plugin');
module.exports={
    entry:'./src/main.js', //指定打包的入口文件
    output:{
        path : __dirname+'/dist', // 注意：__dirname表示webpack.config.js所在目录的绝对路径
        filename:'build.js' //输出文件
    },
    plugins:[
        new htmlwp({
            title: '首页', //生成的页面标题
            filename: 'index.html', //webpack‐dev‐server在内存中生成的文件名称，自动将build注入到这 个页面底部，才能实现自动刷新功能
            template: 'vue_02.html' //根据index1.html这个模板来生成(这个文件请程序员自己生成)
        })
    ]
}

打包的时候出报下面的错

/usr/local/bin/node /usr/local/lib/node_modules/npm/bin/npm-cli.js run dev --scripts-prepend-node-path=auto

原因是因为webpack.config.js是从pdf中复制过来的, 所以字体不对, 删除后从新输入, 问题解决
